Hi there. We have WPML installed on a website that is currently in development. We are using it with ACF Pro, and we do have some plugins we are using as well. We have an English domain and a French domain. Our clients are currently in the population process, and sometimes they notice that when they make a translation of an English page, edit the content to be French, and then add new modules in French only, it sometimes erases content within other modules on the page.
